Gutters must be fit to your roofline properly. If gutters are undersized or overly narrow, they can't handle the rate of water flow from the roof. Misaligned gutters may not set beneath the eaves properly, or their slope may not allow for water flow. A gutter contractor can help you fit your gutters.
Eave damage is one of the biggest concerns of poorly-fit gutters. If the gutter troughs are too narrow or shallow, or poorly positioned beneath the eaves, then water will overflow the gutters and impact the eaves.
Many homes are equipped with wooden eaves. Repeated moisture exposure causes the paint on these wooden gutters to blister and peel, thus revealing the wood beneath to moisture rot issues. Mildew and mold can also grow on eaves, regardless of the material. Further, soffit vent screens may rust out, or moisture may get into the vents and cause mold problems in the attic and on the underside of the roof.
Siding is exposed to water damages similar to the eaves. Water from overflowing or badly-aligned gutters can wash back onto the siding. This is especially a problem on homes with shallow eaves, or on roof lines where shallow or overly level gutters are set too far beneath the eaves.
Water washing down the siding can cause mildew stains on any type of material. Although not immediately harmful, mildew and algae are unattractive and will require work and expense to clean away. Wood siding will also be prone to moisture rot problems. Some of the moisture issues can be counteracted with more frequent painting of wood siding, but there is time and expense involved that is better avoided. Depending on the rate of flow and moisture levels, some damp may actually get behind the siding material and lead to mold growth in the walls.
Gutter fit issues that lead to roof problems are those that cause water to backflow from the gutters and back onto the roof, thus forcing water beneath the edges of the shingles. Gutters that don't have the capacity to route away the rate of water flow can be the culprit. Seamed gutters, particularly those that aren't installed at the proper slope for water flow, are also an issue as seams catch debris and the weak slope further slows water flow.
When water backflows under the shingles, the main issue is an immediate leak into the attic. In winter, the backflow may be from snowmelt, which will then refreeze and cause an ice dam to form.
Contact a gutter contractor if you are concerned that your gutters are causing damages to other parts of your home.
Hi, welcome to my blog. My name is Wendy, and after traveling through many parts of the world as I worked on a degree in anthropology with a minor in architecture, I learned a lot. I saw how people took different approaches to the same issue (putting a roof on their home), but more importantly, I noticed how those approaches were dictated by the climate and culture in the area. Unfortunately, I think a lot of people in North America build roofs that are traditional rather than roofs that are the right fit for the climate. If you are interested in exploring the latter idea, I'm here to help. These posts look at the best way to get a roof that protects you from the elements. Explore, enjoy and send your friends over to my blog. Thanks!
